DEVICE FOR SECURING HANDLES 0F BROOMS," SCRUBBlNG-BRUSHES, &c.

SPEGI'FICA TION forming part of Letters Patent No. 664,413, dated December 25,1900;

Application filed August 18, 1900. Serial No. 27,355. (No model.)

To all whom. it may concern/I" Be it known that I, WILHELM KNIEPER, military pensioner, a Subject of the German Emperor, residingatDortmund, in the Empire of Germany, have invented newan d useful Improvements in Devices for Securing the Handles of Brooms, Scrubbing-Brushes, and other Implements or Tools, of which the following is a specification.

The present invention relates to improved means for securing the handles of brooms, scrubbing-brushes, and other implements or tools, the objects aimed at by the invention being to render the handle easily in terchangeable and to render the connection between the handle and the main body of the broom, scrubbing-brush, and other tool or implement reliable during a prolonged use. 7

Further objects are to simplify and cheapen the construction and to render more efficient, serviceable, and durable in operation this class of devices.

With these ends in view the invention consists in the novel combination and in the peculiar construction, arrangement, and adaptation of parts, all as more fully hereinafter described,show n in the accompanying drawings, and then specifically defined in the appended claims. I

I will now preceed to describe my invention more fully, reference being had to the accompanying drawings, in which- Figure 1 illustrates a vertical section through my improved device. Fig. 2 shows a front elevation of my improved device in its application.

Referring to the drawings, m yim proved device comprises the following parts: A tubular portion a, made of any suitable material, preferably metal, possesses at its lower end a narrower portion 1), in which two hooks c d are located movable around a common pivot. The points of these two hooks point in oppo site directions and are enabled to project from the tubular shaft 1), in which latter openings are provided for the purpose. The two hooks c d constitute the lower members of a pair of joint-levers cf, tothe upper members of which they are pivoted. The tubular portion a is provided at each side with apertures g to enable the movements of theaforesaid joint-levers. The upper arms of the hookscd, which project from the tubular portion a, are provided with outwardly-directed points It 1:.

The upper members efof the joint-levers are provided near their top ends with inwardlydirected points 7c 1, and the top ends of the two members efare shaped to constitute handles, for which purpose they are preferably turned outward.

My improved device, constituted and constructed as hereinbefore described, is employed in the following manner: After insertin g the shaft portion b into the previouslyprepared hole in the broom-body or in the body of any other implement or tool the handle n is pushed into the tubular portion a, when it will encounter the lower members of the joint-levers which carry the hooks c d and h 7;. Continued pressure on the handle n causes these two lower members to turn around their pivot in the shaft 1), thereby forcing the hooks c at out of the shaft b and into the body portion on of the broom or other implement, while the hooks h 2' simultaneously enter said body portion from the top. The upper members efof the joint-levers, which carry on the surfaces facing one another the downwardly-inclined hooks lo 1, are moved downwardly during the aforesaid turning of the lower members of the joint-levers, thereby causing the hooks k l to enter the handle a. Byexercising additional pressure on the handles of the lever members e f the hooks k Z,

h i, and c d are further driven into the handle n and the body portion m, respectively, until the hooks have fully entered same. The parts of the device then occupy the position in regard to the tool and handle which is illustrated in Fig. 2. The separation of the two parts of the tool or implement can be effected in a simple and speedy manner by actuating the angle-levers in a reverse way.

I wish it to be understood that I do not confine myself to the exact construction of the various organs constituting my improved device, as shown and described, as obviously many changes can be made without departing from the spirit of my invention. It is further obvious that the size of the device I00 and the diameter of the tubular portion and of the bottom vend may vary in accordance with requirements.

Having now particularly described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An improved device for securing the handles of brooms, scrubbing-brushes and other implements or tools comprising in combination a tubular portion having a narrower bottom end, and a pair of joint-levers provided with a plurality of hooks acting in opposite directions, substantially as set forth. v

2. Ail-improved device for securing the handles of brooms, scrubbing-brushes and other implements or tools comprising in combination a tubular portion having a narrower bot tom end and a pluralityof lateral openings, and a pair of joint-levers provided with a plurality of books acting in opposite directions, the lower members oftsaid joint-levers as described and shown.

In te'stimony whereof I have hereunto set my hand in presenceof two subscribing wit- HGSSQS.
